Summary

Note how barely visible the node outline is in this screenshot:

On nodes with no overlays, the line is much more visible.

This is a regression from #15634

For an additional issue with the new overlay approach and "flat" nodes such as carpets and snow, see also #15674

Steps to reproduce

Find a node with overlay textures as the examples #15632.
Observe the selection outline indicating the node you are pointing at.
